I prefer to make a design, because I need to let some parts made. I don't have the tools to make everything myself. But I agree that you can easily do it without a cad program.
It isn't that complicated.
It's also more a hobby, now I don't do it for work anymore.
My first trike had the base in 3D and the rest I didn't put in 3d. Just measured it and cut and welded it. I only did the parts that where cut and made by the steel factory.
